The federal government must take decisive action to avoid "a potentially catastrophic loss of animal and plant life," in the national parks, according to a new report that details the effect of global warming on the country's most treasured public lands.

The 53-page report from the National Parks Conservation Assn., a Washington-based advocacy group, contains a litany of concerns related to climate change in the parks, from the bleaching of coral reefs in Florida to the disappearance of high-altitude ponds that nurture yellow-legged frogs in California.

The group, which has offices in California and 10 other states, called on the National Park Service to come up with a detailed plan and funding to adapt to temperature-related ecosystem changes.

"Right now, no national plan exists to manage wildlife throughout their habitat, which often is a patchwork of lands managed by multiple federal agencies, states, tribes, municipalities and private landholders," wrote Tom C. Kiernan, president of the group.
